Write a function to represent the situation

Question

You make tripes to the grocery store to purchase doughnuts . Everytime you go you take a taxi the round trip taxi ride cost 7.00 and each doughnut cost 0.50

y = 7.00 + 0.50x

y = 7.00 - 0.50x

y = 0.50 + 7.00x

y = 7.00 + 0.50

Answer 1

To represent the situation mathematically, we need to identify what the variables represent in the equation:

• Let \( y \) be the total cost of the trip to the grocery store to buy doughnuts.
• Let \( x \) be the number of doughnuts purchased.

Given that the round trip taxi ride costs $7.00 and each doughnut costs $0.50, you can deduce the total cost as follows:

1. The fixed cost for the taxi ride is $7.00.
2. The variable cost for doughnuts is $0.50 multiplied by the number of doughnuts purchased (\( x \)).

Thus, the total cost \( y \) can be expressed as:

\[ y = 7.00 + 0.50x \]

This equation signifies that the total cost consists of the fixed taxi fare plus the cost of the doughnuts purchased.

So, the correct representation from your provided options is:

\( y = 7.00 + 0.50x \)
